DC/DC converter IC
BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ
âGeneral
The PWM type DC/DC converter (BM1Pxxx) for
AC/DC provide an optimum system for all products
that include an electrical outlet.
BM1Pxxx supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
BM1Pxxx built in a HV starter circuit that tolerates
650V, it contributes to low-power consumption.
With switching MOSFET and current detection
resistors as external devices, a higher degree of
design freedom is achieved. Since current mode
control is utilized, current is restricted in each cycle
and excellent performance is demonstrated in
bandwidth and transient response.
At light load, the switching frequency is reduced and
high efficiency is achieved.
A frequency hopping function is also on chip, which
contributes to low EMI.
BM1Pxxx has rich protection.
